Ordering Information
Fluke 771 Milliamp Process Clamp Meter
The Fluke 771 is the latest innovative
approach to measuring mA loop signals.
With the Fluke 771 you no longer need to
lift a wire from a terminal (break the loop)
to measure 4-20 mA which has a direct
impact on your maintenance time. With the
Fluke 771 there is no need to call a control
room to override the control of a process
loop when breaking the loop and you save
time when testing analog I/O on a PLC if
you do not need to check measurements on
a console. In addition, the Fluke 771 can
have another impact on your overall cost
by eliminating catastrophic plant outage
caused by accidentally opening a critical
loop.
